Mosquito Season in Alabama: When to Start Treatment for Best Results
Mosquito season in Alabama runs April through October. Starting in April — before the season builds — is the single biggest factor in having a usable yard all summer.
Timing is everything in mosquito control. Starting in April — before the season builds — is the single biggest factor in having a usable yard all summer.
When does mosquito season start in Alabama?
Mosquito activity begins when daytime temperatures consistently reach 50°F — typically late March or early April around Birmingham and Huntsville. Peak season runs June through August. The season runs through October, with the first hard frost ending it in November. Lake Martin and central Alabama lakefront properties see some of the heaviest pressure in the state.
Why starting in April matters
The mosquito lifecycle runs about 21 days from egg to adult. Start in April and you knock back the early population before it produces two or three more generations. Start in June and you're fighting a population that's already several generations deep — chasing, not managing.
Professional treatment vs. DIY
Backyard foggers kill the adults in front of you right now, then offer no residual protection and don't touch harborage or breeding sites. Professional 30-day barrier treatments keep killing mosquitoes as they return to rest over the following weeks, and treating every 21 days hits the population right before the next generation reaches adulthood.
